Has there been an issue with the translation cache for the enterprise websites?

I am very sure i had my English - Dutch manual translations all covered very nicely. But now everything is back to "google translated" content.The translations covered by gengo are still fine!Please let me know!

After diagnosing the database I have noticed that there was an outage from May 1st to 3rd when our database was making a recovery process. During that process the translations including human translations were lost. You did not notice anything, because our caching system was OK and the issue appeared after the cache expired.
